Aplicación de técnicas de homogenización de series de tiempo de variables oceanográficas, estudio de caso subregión del Pacífico colombiano, como aporte al tema de monitoreo ambiental

Abstract

The present research project makes an application of techniques of statistical homogenization a time series of oceanic variables (temperature, dissolved oxygen and nutrients) for the development of a protocol for the processing of oceanographic data at a thematic, spatial and temporal level; and the subsequent assignment of quality flags, which allow the evaluation of their quality in the framework of environmental monitoring for monitoring the state of marine natural resources. The project presents the methodology developed in the form of an executable code in R and the explanation of the procedures required for the processing of the data. It takes into account elements of climatological, oceanographic, statistical, data management and environmental monitoring, as well as the variation of oceanographic parameters due to phenomena such as El Niño and La Niña. The data used for the application of the methodology correspond to the registry of variables of physical and chemical oceanography, supplied by the Dirección General Maritíma (Dimar) from 1970 to 2016 from the Colombian Pacific as the study area.
